pub const fn fiat_p521_scalar_subborrowx_u64(
arg1: u8,
arg2: u64,
arg3: u64,
) -> (u64, u8)Expand description
The function fiat_p521_scalar_subborrowx_u64 is a subtraction with borrow.
Postconditions: out1 = (-arg1 + arg2 + -arg3) mod 2^64 out2 = -⌊(-arg1 + arg2 + -arg3) / 2^64⌋
Input Bounds: arg1: [0x0 ~> 0x1] arg2: [0x0 ~> 0xffffffffffffffff] arg3: [0x0 ~> 0xffffffffffffffff] Output Bounds: out1: [0x0 ~> 0xffffffffffffffff] out2: [0x0 ~> 0x1]
